I've added traffic policing at 512kbit/s (burst 10kbit) on the IPv6 
tunnel interface (sixxs) on bender for now:

bender:~# tc qdisc add dev sixxs handle ffff: ingress
bender:~# tc filter add dev sixxs parent ffff: protocol ipv6 prio 50 u32 
match u8 0 0 police rate 512kbit burst 10k drop flowid :1


This should take us to the safe side so we can investigate calmly what 
is causing the traffic.

BTW: Is there any HTTP proxy we could/should use? I image at least some 
of the distros running on our VMs are used by Develer as well, so 
sharing a proxy would reduce the (internet) traffic for updates.
